Surface Mount – 600W > SMBJ series

Description

Agency Approvals

The SMBJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

Features

• Excellent clamping capability

• Low incremental surge resistance

• Typical IR less than 1µA above 12V

• For surface mounted applications to optimize board space

• Low profile package• Typical failure mode is

short from over-specified voltage or current

• Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c

• IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact)

• ESD protection of data lines in accordance with IEC 61000-4-2 (IEC801-2)

• EFT protection of data lines in accordance with IEC 61000-4-4 (IEC801-4)

• Built-in strain relief

• Fast response time: typically less than 1.0ps from 0V to BV min

• 600W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles):0.01%

• VBR @TJ= VBR@25°C × (1+αT

x (TJ - 25))

(αT: Temperature Coefficient)

• Glass passivated chip junction

• High temperature soldering guaranteed: 260°C/40 seconds at terminals

• Plastic package has underwriters laboratory flammability 94V-O

• Meet MSL level1, per J-STD-020, LF maximum peak of 260°C• Matte tin lead–free plated• Halogen free and RoHS

compliant

Applications

TVS devices are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Telecom, Computer, Industrial and Consumer electronic applications.
